Xypex Is a System, Not Just One Product
The attached Tetrabuild technical matrix highlights one of the most important ideas behind crystalline waterproofing:

Preventative Waterproofing
Xypex Admix
Introduced during concrete batching so the crystalline waterproofing technology becomes integral to the concrete.
Remedial Waterproofing
Xypex Concentrate
Applied to existing concrete surfaces to introduce crystalline waterproofing into structures that have already been cast.
But the broader Xypex product range also includes products intended for additional waterproofing and repair requirements.
Xypex Modified
Xypex Modified can be used as a second coat over Concentrate where specified, producing a harder finish and reinforcing the crystalline treatment.
It can also be used independently for certain damp-proofing applications on exterior foundation walls.
Xypex Patch'n Plug
Where water is actively entering through cracks, joints or penetrations, Patch'n Plug can be used as part of the repair procedure before the broader waterproofing treatment proceeds.
Xypex Megamix
For damaged concrete requiring more substantial repair, the Xypex Megamix range includes cementitious repair and resurfacing materials.
For example, Megamix II is designed as a repair mortar for patching and resurfacing deteriorated concrete.
This is important because waterproofing severely defective concrete may require repairing the substrate first.
A Typical Tetrabuild Waterproofing Sequence
A proper waterproofing intervention may involve:
1. Inspection and diagnosis Determine where the water is entering and why.
2. Concrete assessment Identify cracking, honeycombing, voids, joints and previous repairs.
3. Active leakage control Stop flowing water where necessary.
4. Concrete repairs Repair defective substrate before waterproofing.
5. Crystalline treatment Use an appropriate preventative or remedial Xypex system.
6. Joint treatment Pay particular attention to construction joints and penetrations.
7. Curing and protection Complete the installation in accordance with product requirements.
8. Inspection and monitoring Verify the treated areas after application.
This is the distinction between applying a waterproofing product and providing a waterproofing solution
