CONVERSION OF AN EXISTING BASEMENT
 |
A
typical dwelling house in a leafy suburb. |
  |
It's basement has gradually become damp over the years and at times of heavy rainfall, suffers from penetrating water, leaving usage limited. The client wished to form a children's playroom and a study. |
 |
Headroom
was limited, so we excavated downwards, formed a concrete oversite,
incorporating temporary polystyrene around the periphery. |
 |
This
was taken out after setting to allow Basement Systems WaterGuard
drainage channels to be installed, linked to a Basement
Systems SuperSump. |
  |
Delta
500 cavity drainage membrane was applied to the walls, taken down
the back of the channels to cause penetrating water to be harmlessly
diverted into the basement water control system.
All walls were fully lined in the membrane to equalize the surfaces and to protect against ordinary rising dampness and salt contamination, all via special fixing plugs sealed back to the membrane where breaching. The membrane was laid upon the concrete oversite and sealed to the wall membrane, with underfloor central heating fitted directly over. The floors were then screeded with a 65mm fibre reinforced compound. Treated timber battens were fitted over the wall membrane via the holes in the fixing plugs, with plasterboard applied. The original features, including chimney breast arches and two light wells were retained. |

The pictures opposite this text show the playroom & study upon completion. The light well window can be seen in the background being that in the second photograph of this set.

The
environment within the basement is now controlled and comfortable,
being very warm, very dry and economical to heat. |
