FAQ'S STRUCTURAL WATERPROOFING

Damp Proofing

Q1 - What is the difference between Aquagard DPC and Homegard DPC?

A1 - Although both products are manufactured from pitch polymer, Aquagard is 1.25mm thick and Homegard 0.9mm thick. This determines their different uses and applications, which are fully described on the relevant data sheets.

Q2 - Can I manufacture an Aquagard cloak on site?

A2 - Marley, supported by the Code of Practice, recommends that you do not manufacture Aquagard cloaks on site, due to the complex nature of the folding and bending required. However, Marley offer a full design and manufacturing service, which actually helps to reduce valuable construction time.

Q3 - What is the minimum lap requirement between a DPC and a DPM?

A3 - In accordance with the Code of Practice, there should be a 50mm minimum sealed overlap between the DPC and the DPM.

Q4 - I am never sure where to finish the cavity fill in relation to the ground level DPC?

A4 - Cavities should be filled to 150mm minimum and preferably 225mm, below the ground level DPC.

Q5 - What is the method for laying a ground level DPC?

A5 - Lay the DPC on a full fresh bed mortar, DPCs should always extend to the full width of the leaf. An additional bed of mortar is then laid on to the DPC followed by the appropriate brick coursing. It is inevitable that the bed thickness at DPC level will be greater than the standard 10mm joint
