Problems with electrical re-wire in my home, with the knowledge after the event that the client can do nothing about it, since Napid requires you to re-use the same contractor to fix the problems. Would you after reading these pages?

We wrote the concerns about the electrical work on 21.03.21; Questions concerning electrics on 21.03.21 and re-wire narrative on 19.04.2021 which had no effect on the credit card company or Napid. So we commisioned the following report to see if that will make any difference.
Pages 10, 11, 12, 13 contain information concerning the condition of the electrical installation of the complete rewiring of my home by Mr Manderson of Manderson Electrical Services Ltd, with the report by a qualified electrician and this statement about the work carried out:-
"The result of my observations and testing, I am recommending that all the fixed wiring be recovered and a complete new fixed wiring installation is installed. Unfortunately the work previously carried out is of such a poor standard I cannot re-use any of it."
Mr Manderson is a Part P Registered Electrician with Napit; Registered Competent Person Electrical; Approved Electrician from Napit; City & Guilds Qualified; Part P Electrical Safety; and Honest & Transparent. His firm was employed to replace all the wiring, power sockets, light switches and lights and make sure that rodents could not attack them to chew through the cables or cause an
electrical problem.
Pages 10 lists 18 electrical faults on the new wiring, re-use of the old wiring, and old wiring that was still either in use or had been cut at the old power socket, at the old light fitting, or old light switch (the plasterers filled an old power socket metal box and short-circuited the fuse - it will be fine in 30 minutes sir; 4 hours later it was still shorting, so presumably that would explain why they switched off one of the fuses in the old fuseboard - see photo on page 15 of the report. As clients; we do appreciate having the opportunity of electrocuting ourselves from their re-wire work) where

• fault 2 is a Code C1 'Danger Present' and immediate action is required from March 2021,
• Faults 4, 12, 14 and 18 are Code C2 and Urgent remedial action required,
• Faults 1, 3, 5, 6, 7, 8, 9, 10, 11, 13, 15, 16, 17 are Code C3 where improvement is recommended

Medway Proposed New School Comments in September 2019

LIKE TREE ROOTS IN THE OPEN GROUND IN GARDENS, TREE ROOTS IN PAVEMENTS REQUIRE WATER, AIR, MINERAL AND ORGANIC MATTER WITH A POPULATION OF MICROSCOPIC ANIMALS OR PLANTS.
WE POUND THEIR ROOTS WITH 40 TON LORRIES, EXCLUDE ALL ACCESS TO WATER, AIR, AND ORGANIC MATTER WHICH THEN KILLS OFF THE SOIL ORGANISMS.
THE TREES SUFFER FURTHER DAMAGE AND WE DO NOTHING ABOUT IT, SO THE TREE ROTS AND FALLS DOWN.
 

"Water is present as thin films covering the soil particles and is retained most readily by soils containing humus and clay. The moisture that plants can absorb is termed available water; that which the soil holds so that plants cannot absorb it, its termed unavailable water. Clay has a greater proportion than sand of unavailable water. More water is conserved in soils whose surface is loose than in those with compact hard surfaces - i.e those under roads and pavements. In the lowest levels of the soil lies the water-table where the soil is completely saturated with water, because it cannot drain away any further. Few plants grown on land can survive with their roots permanently in water.

Soil-air contains a larger composition of carbon dioxide and less oxygen than air above ground. All the underground parts of plants require oxygen.

Mineral matter is formed by the breaking up of the various rocks of which the earth is composed. Many of the mineral salts (carbonates, phosphates and sulphates), which roots absorb from the soil, are dissolved by the soil-water from the mineral particles.

Organic matter is composed of humus, which is the decaying remains of plants and animals. Where plants are growing in a natural state, their dead aerial remains are constantly being added to the surface of the soil and their dead roots and rhizomes to the soil below the surface. Humus is colloidal, absorbing water readily and swelling on doing so.

Soil organisms include moles, mice, earthworms, beetles, larvae, millipedea and centipedes.Earthworms drag down leaves and other plant remains; eat soil/humus and help to mix the soil and render it more fertile. The food of animals consists of complex substances such as carbohydrates and proteins. Plants, although they require the same foods, differ from animals by making these substances for themselves from simpler substances such as water, carbon dioxide and various salts. Many elements are used in the making of a plant's body, and of those one essential element is nitrogen, which is necessary for the manufacture of proteins and other complex nitrogenous products. Although air consists largely of nitrogen, few plants can make use of the free gas as a source of food. It is in the form of soluble nitrates that plants use nitrogen, and it is from the soil that these are obtained. These soluble nitrates are dissolved and washed out of the soil. The nitrates of the soil are chiefly produced by the decomposition of nitrogenous organic matter such as humus and manure. Most plants are quite unable to use organic material directly, but only when it has undergone certain changes.
Method 1. Various soil-organisms, chiefly bacteria, decompose organic matter with the final production of the gas ammonia; other bacteria build up this ammonia into nitrites; and a third group covert the nitrites into nitrates, which are a necessary plant food-material. The addition of manure or some other form of humus like seaweed to soils provide these bacteria with the material necessary for their activities, but it not until nitrates have been formed from it that manure serves as a plant food-material. Oxygen is essential for these bacteria.
Method 2. The second method for production of nitrates is by independent nitrifying bacteria in the soil which build nitrates from atmospheric nitrogen and the
Method 3. by certain nitrifying bacteria associated with the nodules of Leguminous plants, which use atmospheric nitrogen to build up nitrogenous compounds, these become available to the plants themselves during their life and adding organic material, capable of decomposition, to the soil on their death.
A natural source of loss of nitrates from soil is caused by the action of 'de-nitrifying' bacteria, which, in the presence of organic matter and the absence of oxygen, decompose nitrates into free nitrogen." from Plant Ecology bu Hilda Drabble. Published 1937.

Solution
Replace top surface of pavement with CORE TRP SYSTEM and then put the amended shape of paver as detailed in the second row on the right instead of the old concrete pavers or the black/white marble blocks in concrete. This is a modification of the method suggested at the top of Current Permeable Pavement Surface round trees in pavements in Funchal, Madeira Page.

Growth of Pollarded Tree in Pestana Mirimar Hotel Garden in 1 year provides a water solution to this destruction.

When I went to Madeira in January 2018, I discovered that the very large tree in the front garden at the Pestana Mirimar Hotel had been pollarded, leaving only the large stumps of its main branches with no leaf cover at all. When I returned in January 2019, I noted that water sprouts had appeared not just on the pollarded branches but along those same branches. Many of the new water sprouts were over 2 metres in length with large amounts of foliage as can be seen in the photos below.

What was the difference between that tree and others that would be in the main road pavement less than 2 metres away?

• This tree was irrigated.
• This tree had its roots in a large garden of open ground where only the earthen paths had the fallen foliage removed. This fallen foliage would act as an organic mulch to feed the roots of that tree. The ground was shaded by that tree and low vegetation, so that it did not dry out from the heat of the sun or the wind.
• 3 times in the year, it had been fertilised.

Most of the trees in the pavements alongside the main road from Funchal Cathedral to The Forum were neither irrigated, fertilised or had sufficient open ground above their roots for gaseous exchange, root growth or irrigation. As the juvenile tree overgrew its 1 square metre of open ground, it lost all possibility of gaseous exchange or irrigation and thus root regeneration, unless it could get under the pavement and the garden wall to the earth in the garden alongide; if there was one.

The cheapest solution is to take the standard paver of 4 x 8 inches (10 x 20 cms) and reduce it by 3mm each side leaving 1 cm length of the original paver unremoved at the left hand side of each side. When these replace the existing pavers, they leave at section of open space of 3mm round most of the paver. Gaseous exchange and irrigation water thus has access to the roots below; through the weed-control geotextile fabric under the new pavers. This area of pavers can either by irrigated by sprinklers as in the CORE TRP SYSTEM below, or by the lavada irrigation system, where the water can be diverted over the area and any excess gets diverted into the road storm drains. New tree roots will then be created to follow these drainage channels between these pavers. Smooth out the ground level using SHARP SAND NOT BUILDERS SAND (sharp sand being jagged locks together, builders sand is spherical and acts like ball bearings) on top of what is currently below the removed pavers, concrete, tarmc etc, before laying the new pavers. Concrete pavers with either the white or black marble blocks embedded in them could be used to recreate the classic white/black design on some pavements - this would still provide the access to the ground of the new concrete pavers detailed above.
This system could be used for any of the pavements which are not much wider than 40 inches (100 cms) to give the trees a fighting chance. If there are no trees within 8 metres radius of the nearest tree in a pavement, then fill the 3mm space between the pavers with sharp washed sand. This would stop detritus from filling them but still allow for connection to the soil below by the life of that fast-food restaurant.
Side Offlet Kerbs, sometimes known as Weir Kerbs, for use with behind-kerb drainage systems.They often have a cast iron or steel grille for facing to keep the worst of the street litter out of the sewers. Only use the Side Offlet Kerb without a behind drainage system, because 1) the existing drain on the road takes care of the remaining water that falls on the road and that is not used by 2) the ground behind the kerb and a layer of geotextile to prevent the ground from coming out to the road and prevent tree roots from exiting.

One of the solutions is to use the CORE TRP SYSTEM after the tarmac, concrete pavers or marble top surface has been removed from the entire pavement, or for a 144 inch radius from the tree trunk circumference for trees in a non-earth surrounding surface like in a drill ground.
What is the CORE TRP SYSTEM?

• The CORE Tree Root Protection (TRP) System is a CE certified cellular confinement system that provides guaranteed protection for the roots of mature trees from pedestrian and vehicular traffic. It distributes the weight of the traffic which in turn prevents subsoil compaction around the roots.
• With the correct fill material (Download Method Statement to viewgravel retention system, modular paving or porous macadam as the top course) it is completely porous allowing continued water permeation and gaseous exchange to ensure the protected tree stays healthy.
• The system forms a high load bearing, shallow permeable sub-base above ground.

Why is Tree Root Protection Needed?

• Due to the rate of urbanisation within the UK it is becoming increasingly common to find trees located in areas of development with Tree Preservation Orders (TPO’s). TPO’s ensure the protection of mature trees, especially when construction work is being carried out nearby.
• Our CORE tree root protection (TRP) system offers a compliant solution to creating a driveway, car park, road or track for temporary site access. The system creates a three dimensional erosion barrier and structural bridge that uniformly distributes weight-bearing loads preventing unwanted ground compaction in and around the feeder roots of the tree.

Then, provide a sprinkler system which waters that area at some period between 01:00 and 05:00 when it is likely to have minimal use by people. The time period each night of irrigation and how many nights per 4 weeks can be worked out by trial and error - Above Pestana Mirimar Hotel reception area is a swimming pool. Alongside this pool is a paved area and a 12.5 metre radius grassed area with 3 mature palm trees. This area is irrigated by 5 pop-up sprinklers at times not to inconvenience the guests in the suites round this area on the third floor, when they go for a swim.

Photo 1 - tree 80 from pestana mirimar in mirimar front garden IMG_6440.JPG

Raintree tree in the front garden of the Pestana Mirimar Hotel. The branches were cut off leaving stumps, no foliage or small branches were left on the tree at least 12 months ago i.e in January 2018 or earlier. All the foliage you see in the following photos has been generated in the last year.

Now if the trees in the pavement had the same access to a large area of open ground, was irrigated and fertilised then they could have the same amount of shade bearing foliage. Not everyone wants to fry on their walk to the English Church in the centre of Funchal on Sunday.

There is open ground this side of the Forum and also on the other side - it is intended to build some more hotels on those sites. That would make several kilometres of concrete, where the present inaction on these pavement trees will kill them or make them so dangerous that they will be cut down and leave hotspots, which might be fine for the inhabitants, but could be very uncomfortable for the visitors.

Part of the Raintree tree in the front garden of the Pestana Mirimar Hotel

This top growth has grown during the last year, through regular watering and application of 3 lots of fertiliser in that year, by growing watersprouts.

Photo 3 - tree 80 from pestana mirimar in mirimar front garden IMG_0007.JPG

Here is the detail of the Raintree shown in the previous photo. The watersprouts in the left branch come from buds in the branch, whereas the watersprouts on the right branch come from water/sugar bearing layer at the edge of the original branch cut. You can see that these adventitious shoots may have grown large and long, but there is inherent weakness in the left hand branch watersprouts because too many are sharing the same spot of attachment to the branch. The watersprouts on the right hand side are only joined to a very small section of the living tissue and outside bark and so have a weak joint.

Photo 4 - ee 27 from end of 2 road junction with bleeding cut stumps IMG_6235.JPG

You can see where the sap is bleeding from these cut stumps and that is the width of the connection of the watersprout to this cut end if it develops later. The wood inside that ring of sap is the heartwood and completely dead, so there is no way that that heartwood can join to the watersprout and provide the rigidy and strength required at the juncture between a branch and the parent branch or trunk.

Photo 5 - tree 32 from end of 2 road junction with watershoot and proper branch IMG_6259.JPG

It is a new branch on the left which will become considerably stronger than the watershoot on the right.

The following was written on the Welcome Page in February 2018:-

"A tree in the front garden of the Miramar Hotel within 200 cms of the roadside pavement has been very recently pruned using the same cutting procedure as indicated in (4) of Fig. 13. above with each cut end being at least 15 cms in diameter. It left a trunk and bare branch network covering at least 10 metres width. Unfortunately there was a storm and the wind reduction enjoyed by the tree next to the hotel reception swayed to within 5 cms of the concrete balustrade above that reception area, whilst I watched it from my hotel suites lounge. The trunks of the palm trees that were higher than that tree hardly moved and only their topgrowth of leaves thrashed around. There is a swimming pool above the reception and office area and I do hope that those staff are supplied with diving suits and oxygen tanks. I suspect that nobody did a risk assessment on the result of removal of all foliage and topgrowth of that pruned tree which vastly reduced the wing speed before hitting the trunk swaying tree further up the hill.

None of the cut ends of the tree in the front garden of the Miramar had any protective dressing.
Page 6 of the pruning book by Brown states the following:-
The Protective Dressing
When a cut is made, a considerable amount of heartwood is exposed which, in the case of larger stems and branches, has become salignified or hardened to give mechanical strength. This remains healthy and perfectly preserved, provided it is protected from air and water, pests and other harmful organisms and the tree is in a healthy condition. The cut immediately exposes this wood and it is vital, therefore, to protect it as speedliy as possible before the destructive agents begin their work. It will be apparent how quickly a sealant must be applied, when it is realised that the air is full of spores of all kinds which may alight on the cut surface at any time. All cuts over 25mm (1 inch) in diameter should be treated, although with young specimens even smaller wounds should be dressed. The material used must be waterproof. It should retain its pliable nature for a long period without cracking. It should not be favourable to the development of diseases or pests - in fact the ideal dressing would have an active and lasting fungicidal property. It is necessary to look over the wounds at least annually and, if necessary, make further applications, although a 6-monthly inspection of every tree is in any case is advisable, and it would be natural to inspect wounds at the same time. Often, radial cracks appear in the heartwood on the surface of a large wound as it dries out.
I have never seen any protective dressing on any of the trees in Funchal."

Photo 10 - tree 80 from pestana mirimar in mirimar front garden IMG_0174.JPG

The circular lawn area here is about 12.5 metres in radius and you can see 2 of the 3 palm tree trunks on the right hand side. This area is irrigated with 5 pop-up sprinklers. This entire lawn area is supported by the concrete ceiling of the Pestana Mirimar Hotel Reception area below. Those very healthy-looking palm trees appear as if they were planted fairly soon after this part of the hotel was built and they have been irrigated and fertilised in a very shallow depth of soil ever since.

These palm trees have a large ground area to put their roots in. Due to the excess of water on the island the detrimental effect of grass growing over the roots of these palms can be overcome.

In England a friend had a plum tree growing on a sloping lawn, which was dying. I dug into the lawn and pulled it back to reveal bone dry ground under the turf even though it had rained heavily the previous night. I removed the turf radius 24 inches from the trunk and put some dead autumn leaves over that bare ground. I advised that lawn mowings should be apllied as a mulch. It wasn't and that area of ground became bare. The tree died that year.

Photo 11 - tree 38 from pestana promenade outside porto mare hotel IMG_6293.JPG

This tree outside PortoMare Hotel has grown very well and the following photo indicates that it is in a very narrow bed, but at least you can see the irrigation system and it was also probably fertilised. This flower bed is long with other vegetation in it to prevent the sun and wind from drying the soil. It allows the roots of this tree to go a long way on each side to support itself and to have feeder roots and gaseous exchange.

So, it can be done and also done without either pollarding the tree before it was transplanted or later in its life.

Photo 14 - tree 80 from pestana mirimar in mirimar front garden tree root by pavement IMG_0187.JPG

Lateral roots near the soil surface thicken over successive years, eventually becoming the large woody roots of the framework root system of a mature tree - there are usually between 4 and 11 such roots which may become 30cm (12 inches) or more in diameter close to the stem.They taper rapidly until at 200-300 cms (80-120 inches) distance they are usually only 2-5 cm (1-2 inches) in diameter, by which stage they have lost much of their rigidity and physical strength. It is here that they tend to break when root plate failure occurs, e.g in a storm. Beyond the 'zone of rapid taper', lateral roots extend outwards in a broad zone for many metres, without appreciable further decrease in size - typically maintaining a diameter of 1-2 cm (0.5-1 inch). They are sparsley branched, perennial, woody and rope-like in appearance. Although most rope-like roots are only 500-1500 cms (200-600 inches) long, some can be 2500 cms (1000 inches) or more in length.

This is one of those lateral roots from the Raintree tree.
