Abstract | Traditional practises employed in designing and installing peripheral drainage systems around subgrade construction have not been entirely successful, particularly where the basement space is to be finished. A new method is introduced where drainage along the basement wall takes place in a 10 mm mineral wool layer having a density of 50 kg/m[3]. In the experiment two such layers were placed against the foundation wall. This new method is a modification of the standard method of replacing free draining backfill. It would have the two fold purpose of providing a free draining layer so that water could readily reach the footing drains and also supply a heat insulating layer on the outside of the foundation. Laboratory tests simulating field conditions indicate that glass wool mats make a suitable draining and capillary disrupting layer against a basement wall, provided that, as always, satisfactory draining around the foot of the foundation was provided. Laid in two layers and without continuous joints, the glass wool mats used in the Norwegian Building Research Institute test setups showed better properties than the more conventional techniques they were compared with. No water penetration was recorded and the mats showed no sign of plugging. The Norwegian Building Research Institute hopes to be able to test several other ways of draining basement walls so that different solutions for different applications can be recommended. |
