In the construction industry, crack management is essential to guarantee the durability and safety of structures. Among the solutions available, SPUR (polyurethane) foam has established itself as an effective method for injecting into cracks. But what is SPUR foam, and in what situations is it recommended? Let’s explore the benefits and features of this essential product for the construction industry.
What is SPUR foam?
SPUR foam is a two-component polyurethane foam which, once injected, expands to fill cracks and voids in concrete structures. It is particularly suitable for non-structural cracks and those exposed to moisture. Its ability to adapt to building movements makes it the solution of choice for ensuring watertightness and durability of repairs.
Advantages of SPUR foam
Using SPUR foam offers a number of significant advantages :
-
Superior waterproofing: SPUR foam forms an impermeable barrier, effectively preventing water infiltration, even in wet conditions.
-
Flexibility: Unlike other materials, SPUR foam remains flexible after curing, allowing it to follow the natural movements of structures without cracking.
-
Rapid application: Thanks to its fast reaction time, SPUR foam cures in just a few minutes, reducing intervention time and disruption on site.
-
Moisture compatibility: It can be injected into damp cracks, making it ideal for environments prone to damp or water ingress.
SPUR foam applications in the building industry
SPUR foam is used in a variety of situations to ensure the integrity of structures.
1. Repairing cracks in foundations
Foundations can develop cracks due to ground movement or climatic conditions. SPUR foam injection seals these cracks, preventing water infiltration and structural damage.
2. Waterproofing basement walls
Basement walls are often exposed to damp. SPUR foam offers an effective solution for sealing cracks and preventing water penetration, protecting the interior of the building.
3. Repairing concrete slabs
Concrete slabs, whether on the ground or suspended, can develop cracks over time. SPUR foam injection restores the integrity of these slabs without the need for complete replacement.

Application of SPUR foam injection
SPUR foam is generally applied in the following stages.
-
Crack preparation: The area is cleaned to remove debris and ensure good adhesion.
-
Installation of injection ports: Ports are placed along the crack to allow even distribution of the foam.
-
Foam injection: SPUR foam is injected under pressure, filling the crack and expanding to fill voids.
-
Curing and finishing: After curing, the ports are removed and the surface is cleaned for a clean finish.
