Basement Retaining Walls

Waterproofing Basement Retaining Wall Structures on the exterior or positive side of the Basement Wall

Drizoro Basement Waterproofing Materials required:

  1. Prepare treatment areas. Remove all loose material and efflorescence ensuring a clean and sound surface.
  2. Any damage to the surface should be repaired using Drizoro Maxrest.
  3. Any missing mortar can be replaced with either Drizoro Maxrest or Drizoro Maxplug
  4. Apply Two coats Drizoro Maxseal Flex X 150mm cover over footing & wall joint incorporating Drizoro Maxmesh into the first coat
  5. Allow 14 hours minimum between coats.
  6. Two coats of Drizoro Maxseal Foundation | Drizoro Maxseal  can be applied to all other rigid surface are as of the wall, 50mm overlap onto the cured Drizoro Maxseal Flex
  7. Leave 4 to 7 days before backfilling if required
  8. Rain expected. (within 5 hrs do not apply)
  9. If backfilling space is an issue. The coating is applied as the wall is being constructed.
  10. Do not place plastic membrane or the like immediately after coating.
  11. Any external penetrations require Drizoro Maxplug and a coating of Drizoro Maxseal Flex incorporating Drizoro Maxmesh

Interior Cementitious Basement Waterproofing

The refurbishment of external basement waterproofing is difficult, if not impossible, and the cost is usually enormous. Excavation, making the excavation safe. Waterproofing basement retaining walls internally is cost effective and prevent degradation of the wall.

Basement Retaining Walls, Basement Waterproofing-internal-ingress-seepageThe need for using an interior repair to a basement wall is usually self-evident by the presence of:

  1. a persistent musty smell
  2. dampness in the wall
  3. presence of mould – not healthy
  4. effervescence salt build-up
  5. changes in the water table may cause seepage or leaking
Avoid Expensive Treatment Methods

Before attempting expensive repairs check to see if it’s just condensation on the wall rectified simply by dehumidifying the basement area. Note- incorrect runoff. Runoff should be away from the walls. This is of greater concern in high rainfall areas.

No matter what arises to cause the problem of a damp or leaking basement. To prevent worse problems from developing, the best way forward is to fix it is to seal the wall completely using Drizoro Products Drizoro Maxseal Flex | Drizoro Maxseal Foundation | Drizoro Maxseal | Drizoro Maxjoint Elastic which can seal even high hydrostatic water pressure. Many recommend the use of sump pumps but according to David Cook’s

“This is a very common yet misguided solution that is used all over the country. The idea behind fitting a sump pump is born out of ignorance, the “you can’t stop it, pump it out” mentality is steeped in danger!”

In the first instance. You are breaking into a structurally designed reinforced concrete base. Slabs are designed to take certain loadings.  Buildings walls and possibly other areas of the building. This raft WILL NOT have been designed for someone to come along and cut a hole into the concrete which will invariably involve exposing the steel reinforcing or worse cutting through it.”
