During a damp proofing installation, we were asked to install a high quality real timber floor covering (engineered real timber laminate flooring). This type of flooring is sensitive to dampness and requires a dry, flat, level and stable substrate on which to be laid.
Prior to installation of the new timber flooring, David carried out a survey of the existing suspended timber floor. The hallway floor was found to be damp and out of level with excessive vertical movement (springy). David carried out some invasive investigation work, removing some floor boards and found the timber joists underneath to be wet and decayed. The end bearings had lost depth due to decay causing deformation of the floor surface.
There was approximately 10cm of standing water on the floor of the sub-floor void throughout the property which we considered was contributing to the damp and decay problem in the floor. In addition an incoming electrical supply main was submerged in the standing water causing some safety concerns.
David carried out some research with neighbours and found many properties in the area suffered similar problems.
DRYabode carried out the following works to deal with the problems we faced:
- Installation of a sump chamber and automatic sump pump in the floor of the sub-floor void.
Removal of the existing floor joists and boards.
- Installation of new pressure preservative treated joists with the bearings isolated from brickwork by wrapping the ends in plastic damp proof course.
- Damp resistant tongue and groove floor boards with an access hatch providing maintenance access to the sump pump and chamber below.
We have now installed the high quality engineered beautiful timber laminate flooring successfully and our clients have the peace of mind that care has been taken in ensuring their new floor will provide many years of service. The damp proofing scheme has also been successful.
