Basement Waterproofing contractors
Basement Conversion / Cellar conversion Mid terrace property, Birmingham area
This reasonably sized basement, that had previously been used for storage only. Our client was looking for a basement waterproofing company to carry out a cellar conversion project, to create a gaming room.
The basement suffered from damp and frequent flooding. In order to resolve these problems, we decided to install a basement tanking cavity drainage membrane system, type C waterproofing system. Before commencing a basement conversion project, its essential to careful consider the layout of existing pipework present in the basement and electric cabling. Once considered, necessary adjustments must be made prior to commencement of the conversion project.
Regarding the sump pump, the ideal area was located after careful consideration. A cavity was dug out to house the sump chamber for the twin sump pump. The route out for the discharge pipe was determined and connected to the nearest drainage point. An inspection hatch has been created for the sump pump and servicing points of perimeter drainage channel. These will need to be inspected annually to ensure continuous good working order.
We then installed our basement waterproofing, in the form of a raised flooring membrane system to the floor area and a perimeter drainage system. This is to collect any flooding water and direct it into the sump chamber, so that water can be discharged, keeping the basement floor dry.
Basement tanking, in the form of a cavity drainage membrane system has also been installed in the stairwell, sealing the stairs as required before fitted tread caps are installed to the stairs, so that carpet or flooring can be fitted to the stairs with ease.
Regarding the walls, firstly, we remove all wall plaster back to bare brick. We then installed another basement tanking / basement waterproofing system, or cavity drainage membrane system to all walls areas, below ground level and stairwell area, floor to ceiling height, overlapping wall and ceiling junctions with specialist sealing tap. The fixings required to attach the basement waterproofing membrane to the wall are self-sealing brick plug, which prevent moisture from tracking back through. To finish wall surfaces, we applied plasterboard to all wall surfaces, hiding cables and pipework, and then a plaster skim to all wall areas to achieve a smooth finish. We also applied pre-treated pressure treated timbers lining to exterior wall surfaces. This is the opportunity to straighten the walls not currently plumb. At this point also we have, insulated walls with insulation panels, to increase thermal efficiency of the walls, preventing heat loss from the area.
We assessed the existing ventilation and decided in was necessary to install additional ventilation to area. It is very important to do so as basements are notorious for poor air flow, causing condensation and mould / mildew
An existing window was replaced with a modern PVC window unit, which increased the natural light in the room.
Tongue and groove floating timber floor sheeting was applied to floor area, so the customer can lay carpet or flooring of their choice.
Finally, unsightly utility meters were concealed and boxed in, with service hatches.
