Damp Proofing in Hengoed

Extensions such as garage conversions will typically require additional damp proofing to be added as part of conversion, as the pre-existing garage will often have a single skin design for walls and floors, which was not built to be in accordance with building regulations for habitable rooms. This damp proofing will have to be added to walls and floors. In addition, the roofing of the garage conversion will require water proofing. The damp proofing of the floor of the garage conversion will usually be achieved by using a damp proof membrane. This membrane is available in either solid or liquid form. The damp proof membrane will be put down either on top of the pre-existing concrete floor, underneath the new floor, or as part of both, depending on whether the floor will be a solid or a floating floor. In a few garages, the walls will have already been damp proofed, but this might need to be updated as part of the conversion in order to comply with current building regulations. The walls should be damp proofed in order to safeguard the brickwork from rotting gradually as moisture sets in. This can be accomplished by either applying damp proof membranes, waterproof rendering, or cavity insulation, depending on the type of walls already present in the garage. Damp proofing is a part of the building regulations that the garage conversion will need to adhere to, therefore is it important to make sure that your garage conversion incorporates suitable damp proofing methods.

Hengoed

Hengoed is a town on the west side of the Rhymney Valley - in between Ystrad Mynach to the south and Cefn Hengoed to the north. Throughout the valley it looks in the direction of Maesycwmmer. The village remains in the county borough of Caerphilly, in the traditional county of Glamorgan, Wales. The name literally implies 'old timber' in the Welsh language. The selecting ward of Hengoed consists of the villages of Hengoed and Cefn Hengoed as well as a part of Tir-y-Berth in the north west. The ward population was recorded at 5,548 in the 2011 census, a boost of 10% over the previous ten years (2001 = 5,046), due partially to a number of new-build housing developments in the ward between 2001 as well as 2011.

FAQs

How quickly can I redecorate my walls after damp proofing has been installed?

You should make sure that all signs of damp have gone before you redecorate your walls. If you want to paint your walls with a water-permeable emulsion paint, you can usually do this after 1 or 2 months. For other types of decoration you should wait longer.

How can I tell if my property has damp?

There are a few visible signs of damp, although it often goes undetected. However, in older or empty properties, this made become detectable through its smell. These include peeling paint and wallpaper, crumbling plaster, mould growth, black spots or spores on walls and ceilings, and rotting skirting boards and flooring.

How can I tell what type of damp I’ve got?

Signs of rising damp tend to be close to the ground, usually no higher than a metre. It usually works its way up walls in horizontal lines. Penetrating damp usually develops in patches and can often be much higher up. For more advice, speak to a damp proofing professional.

Why is it important to fix a damp problem?

Damp is a serious problem, particularly if you live in an old property, because it can lead to structural damage. This will cost you big money and could be very dangerous, to yourself and the property. Take damp seriously and get it inspected and resolved as soon as you discover it!
