Dryzone has been succesfully used over the past 6 years to treat rising damp in thousands of properties. Its concentrated cream formulation is able to deliver the right amount of active ingredient into the damp wall in one injection.  This easy to use cream allows anyone to install a damp proof course in their home without the use of a mechanical pump but with a simple Dryzone injection gun, heres how:

How much Dryzone do I need?

This easy to use table demonstrates how many 600ml Tubes of Dryzone are required.

How do I prepare the area?

Remove skirting boards and render to expose the mortar to be treated.

How and where do I drill the injection holes?

The Dryzone System requires 12mm holes to be drilled directly into the mortar course, centres no greater than 120mm apart. See the chart below for the different wall thickness.

How do I inject the Dryzone?

Insert the brass nozzle of the Dryzone gun into the full depth of the drilled hole. Gently squeeze the trigger of the gun slowly pulling back the gun until the hole is full within 1cm of the surface. Either plug or point over the injection holes.

How do I Replaster following the installation of the Damp Proof Course?

Replastering following a Damp proof Course must be done correctly or the Damp Proof Course can fail. It is advisable to allow 2 weeks before you replaster.  Remove and replace any salt-contaminated plaster using a 3:1 sand-cement render incorporating Renderpel plaster additive. It is imperitive not to use Gypsum based products.
