What is DE NEEF® polyurea grout?

When foundation cracks are actively leaking, DE NEEF® polyurea grout injection is one of the most effective ways to stop water and protect your home. At Crack Attack, we use DE NEEF® to seal leaking foundation cracks throughout Colorado, preventing moisture intrusion before it can cause further damage. This hydrophilic grout expands upon contact with water, penetrating deep into the crack to form a flexible, watertight seal. Whether the leak is in your crawlspace, basement, or garage, our team delivers clean, professional repairs that restore your foundation’s integrity and keep your home dry.

Our Foundation Crack Repair Process: Using DE NEEF® Injection

Our leaking foundation crack repair process starts with a free evaluation, where our team thoroughly inspects your foundation to locate the source of water intrusion and determine the best repair method. Once the plan is in place, the crack is cleaned and prepared to allow the DE NEEF® polyurea grout to penetrate effectively. This hydrophilic grout is then injected under low pressure, where it reacts with water and expands deep within the crack to form a flexible, watertight seal. The result is a long-lasting repair that stops active leaks and helps protect your home from future water damage.

Epoxy Injection Solutions for Foundation Cracks

Epoxy injection is one of the most effective methods for repairing cracked foundation walls and restoring their structural integrity. This process uses a high-strength, commercial-grade epoxy resin that penetrates deep into the crack, bonding the concrete back together from the inside out. Once cured, the epoxy forms a rigid, structural seal that not only stops moisture intrusion but also prevents further movement or widening of the crack. Ideal for vertical and diagonal cracks in basements, crawlspaces, and garages, epoxy injection provides a long-lasting solution that keeps your foundation strong, stable, and secure.

Carbon Fiber Solutions for Structural Cracks

Fortress Stabilization Systems™, including the Crack Stitch system, are advanced reinforcement solutions used to stabilize and strengthen cracked foundation walls. Installed across or along the crack, they work in conjunction with other repairs - such as epoxy injection, to provide additional structural support. The high tensile strength of carbon fiber, combined with its lightweight and non-corrosive properties, makes it an ideal long-term solution for preventing further movement, widening, or re-opening of the crack. Once bonded to the concrete with epoxy, these reinforcements become part of the wall itself protecting your foundation for decades.

Rebar Repair Solutions for Spalling Cracks

Rebar repair involves restoring and reinforcing damaged steel reinforcement and the surrounding concrete to ensure the foundation’s strength and longevity. At Crack Attack, we begin by removing deteriorated or spalled concrete to expose the corroded rebar. The steel is then cleaned, treated, and primed to halt further corrosion. Once prepared, the area is rebuilt using a high-strength, fiber-reinforced or non-shrink grout that bonds securely to the existing structure. This process not only restores the concrete’s integrity but also reinforces the embedded rebar, ensuring long-term durability and stability for your foundation.
