advice on heave please

[treerat rob]

How would you guys recommend removing 4 seventy foot poplars growing 20 feet away from a property on heavy clay soil. The TPO's have been lifted and the house,which is about 20 years old is subsiding. The customer is in negotiations with the insurance company. The trees have been crown raised to 5m, 2years ago and are in extremely good condition. The trunk diameter is approx 2 ft across. Would you suggest removing in 2 or 3 stages and if so,how long would you leave between each process. :confused:confused1:

Have you been instructed by either the client or the insurance company to remove the trees or have you been asked for advice on the best method?

If the insurance company is involved then they should have a say on it. If the house is subsiding the trees will be a contributory factor only. Subsidance is usually caused by poor foundation design. The house will have to be underpinned so a bit of heave will probably help the house sit back together. If the house had been properly constructed in the first place it would be able to cope with a bit of movement in a plastic subsoil either way, up or down. Given that the rainfall is so unpredictable no-one would be able to predict the amount of soil movement post pruning/felling so take the fookers down and be done with it.

Its probably a better idea to remove the house.

Unless you are qualified and insured to provide advice on subsidence issues leave well alone ,forget advice from this forum on how best to do the job, unless you can obtain a clear spec from the insurance company's appointed Arb consultant , just pass the job on. The water demand of Poplar is High and the influencing distance is indicated as being calculated on modified plasticity index 36 eg only taking into account tree height @25m, not actual , 31.25m (zone of influence) there is a lot to consider , you also need to know actual foundation depth and type, and precise soil plasticity index , it is late and please don't every one jump on me, i do produce these things for a living , one other consideration is the current condition of the trees, and past and current climatic variations. hope that helps. eg only of things to consider .

B4 i go to bed let me put this another way, lets say best price for clear felling this site £1600, hows that b4 you all jump on me, lets then say subsidence issues continue and you are then named within the report as being the possible reason for the continued problem, how much do you think your first representation from your solicitor will be?
