Methods of Damp Proofing
Know about different techniques that can be used to prevent or minimise the occurrence of dampness in your house.
Chemical Impregnation Under Gravity
In this method, holes are made at regular intervals in the mortar lines, and special tubes are then placed. Water is then made to flow down the said holes, forming a horizontal water-repellent layer on the bricks and mortar.
Chemical Injection Under Pressure
Like in the previous process, water is forced into the holes that have been drilled, thus ensuring optimal soaking and waterproofing.
Physical Damp Course Installation
This wall moisture barrier entails cutting a row of bricks just below floor level and fitting in a plastic layer; the old mortar is then replaced with waterproof mortar. Every course is pointed with mortar, and then it is left to cure before laying the next course; this makes it strong.
Replacing Plaster or Plasterboard
The damaged plaster or plasterboard is removed and replaced with waterproof plaster or cement mix on the wall structure. Wall sealing is also a solution. Slatting may be fixed to provide an air gap for ventilation and moisture control.
Damp proofing specialists provide a range of services that include subfloor ventilation, rising damp control, roof ventilation, mould control, underfloor and basement damp proofing, home damp inspection, and air purification.
How Much Does Damp Proofing Cost?
It is difficult to estimate exactly how much damp proofing costs, as these can fluctuate greatly depending on the specifics of a particular situation. Every damp wall repair service job is different, and each requires consultation with a damp proofing expert to identify the cause and extent of dampness.
Factors Affecting Costs
Damp proofing entails placing a certain quantity of damp course, and it is common practice for professionals to be paid a base rate for the service. On the other hand, an hourly rate might include the preparation of the site, installation, and reapplication of plaster. Severe cases of dampness that would warrant a second trip to perform repairs are likely to be more expensive due to the time taken. You can consider all factors to hiring an affordable damp proofing service.
Expected Costs
As for the damp proofing, the expenses of damp proofing may vary from $150 to $1000 per linear metre, though it depends on the size and scope of work. Professional sub-floor ventilation may cost between $900 and $3500, depending on the extent, while chemical treatments may cost $75 to $300 per linear metre. Damp repair experts charge varies depending on the type of damp, the extent of the damage, and the services required. Basic treatments, like installing a new damp-proof course and addressing minor salt damp issues, can range from $2,000 to $5,000.
When deciding which damp proofer to choose, get damp survey, several quotations, and check that the company is reliable. Always ask for a written assurance of the work done to avoid any future problems.
