Basement conversion for homeowners in Lichfield
Products Used: cavity drain membrane, perimeter drainage channel, sump and pump chamber
Surrounded by unspoilt countryside and just north of the industrial city of Birmingham lies Lichfield, a cathedral city and civil parish in Staffordshire. The city centre retains its Georgian charm while delivering contemporary shopping and restaurants for its residents. A stone’s throw away from Beacon Park in the city centre lies a traditional character property which was in need of basement waterproofing to create a dry storage area.
Being a terrace home, the customer knew they were restricted and could not extend there home above ground. A basement conversion was the logical next step and they knew Timberwise were experts in the waterproofing of basements and vaults. They were confident that Timberwise were able to create the extra dry space they needed.
The property is a two-storey domestic house. From the ground floor, solid brick steps lead to the cellar where a flood had previously occurred due to a utility service failure. The basement itself is constructed of traditional brick, with an arched ceiling below the front room of the property; there was no evidence of any previous waterproofing. The basement benefitted from a large radiator and power supplies allowing the space to be utilised for storage.
The Waterproofing Solution Methodology
The desired outcome of the project was that the customer was left with a dry storage space, so in accordance the current British Standard – BS8102:2009 “The Code of Practice for Protection of Below Ground Structures Against Water from the Ground” – a cavity drainage system was recommended as the most reliable and robust waterproofing system for the job.
Cavity Drain Membrane
This particular solution was perfect for the customer as it prevents any running water or vapour from entering the basement so ensuring that all internal wall and floor finishes remain dry in the future. Timberwise installed the cavity drain membrane with specially patented fixings, the fixings had gasket seals to ensure that the membrane remains “sealed” and would not let moisture through.
Perimeter Drain Channel
This is the piping system engineered specifically to
solve basement water problems effectively without worry of
clogging from soils under the floor. It has large holes in the back to
accept water and a flange with special segments
The TripleSafe pumping station forms the heart of the Type C waterproofing system. The sump pump stands in a hole which is dug in the lowest part of the basement. As the chamber fills with water, the pumps float switches are triggered and activate the pumps. This pumping station has many unique features such as the special pump stands (which keep the pumps off the bottom of the sump chamber away from silt that may clog the pump), the warning alarm (that sounds in the event of failure or rising of water), and the sealed lid (for safety).
The pumps themselves have heavy-duty poly-coated cast iron casings each with a large diameter discharge pipe. Also included is a battery backup pump and heavy-duty battery which activates should there be a power failure. As the name suggests the TripleSafe benefits from having 3 pumps.
Timberwise provided a 10-year guarantee for both product and workmanship, offering the customer real “peace-of-mind” for the basement waterproofing system.
The customer knew it was vitally important that the new system is maintained, as without a regular pump service it would invalidate the system’s long-term guarantee.
As a result, they took advantage of Timberwise’s “annual clean and check”. This then ensures that at the time of the visit Timberwise will check and clean the sump and pump system, change the alarm battery, test the alarm, and check the channel.
