Strength you can build on

More than double the required strength

Stumbelbloc has been submitted to the Standards Association of Zimbabwe for independent testing. The blocks achieved a compressive strength of over twice the minimum required by the Standards, and the BlockGrip adhesive bonds up to fifteen times stronger than conventional mortar.

• Independently tested for compressive strength against the national building standard.
• Every block is manufactured to a consistent, repeatable dimension for predictable results.
• The BlockGrip adhesive is formulated to exceed the bonding performance of traditional mortar.
• Suitable for load-bearing walls, boundary walls, and full structures up to approved heights.
