Association members helps Main contractor on site of new care home
Association member Broadoak Preservations has managed to help in the design of an waterproofing system at a listed group of buildings in Cheshire.
The building is being transformed into a care home and drop in centre and has lots of renovation issues, but Broadoak was there to advise on the solution of soil retaining walls which were approx 1 metre in places below the internal floor levels , after careful consideration Jason from Broadoak decided that cement based systems were inpractical due to animal storage (uric acid issues) and also very poor quality bedding material issues also, along with not wanting to hinder the breathing issues of the solid brickwork.
A cavity drain system , had been recommended and was drawn into the plans but as these walls were underground this did not comply with bs8102 as there were no drainage capabilities to the design,
A new design has been submitted and approved along with cavity membranes and a perimeter drain linking in with a drain within the structure.
Not a full basement , but this shows using the principals of designs from basement applications can provide solutions that can benefit buildings which are only partially below ground.
The water table in the area was quiet high also so the existing design had a failure potential and now the system has been designed to comply with any water coming to bear on the walls gives the main contractor peace of mind but also gives him a guarantee solution for building control and the client.
