Adhesives, Crack Repair and Structural Strengthening

Systems for adhering and bonding to stone and masonry; crack repair in stone, masonry and concrete; and strengthening of masonry and concrete.


Ruregold FRCM

Ruregold FRCM is a structural strengthening system with bi-directional carbon mesh and stabilized inorganic matrix for masonry constructions. The increased weight of carbon makes it suitable for applications on masonry such as wraps or shear or bending reinforcements. This strengthening system does NOT use epoxy resins and its performance equals that of traditional FRPs with carbon fibers and epoxy binder.

*Ruregold products are structural strengthening systems for concrete and masonry that require design and oversight by a licensed professional engineer. Referrals for third party independent engineering services with expertise in FRCM design are available upon request.

Flex-Seal 510u

Flexi-Seal 510, 510-U Crack Sealants

FLEXI-SEAL 510 & 510-U are two-component, highly flexible 100% solids epoxies. They are designed to fill, bridge and seal small "working" cracks in stone, concrete, and masonry. They are particularly useful for sealing and waterproofing cracks up to 1/8" wide such as settling cracks, flexural (negative moment) cracks and construction joints.

Flexi-Weld 520T

Flexi-Weld 520, 520T Masonry Adhesives

FLEXI-WELD 520 and 520-T are two-component, moisture insensitive, high strength 100% solids epoxy adhesives for general purpose bonding to a wide variety of substrates, including stone, masonry and dry or damp concrete.

Flexi-Fill 530

Flexi-Fill 530 Crack Filler

FLEXI-FILL 530 is a unique two-component, slightly flexibilized 100% solids epoxy-acrylate-isocyanate terpolymer adhesive for surface-sealing cracks and filling small depressions in a wide variety of substrates. Suitable substrates include terra cotta, concrete, masonry and stone. FLEXI-FILL 530 is a paste adhesive, which should be used neat or mixed with coarse fillers and tooled onto bonding surfaces. Although it is packaged in premeasured "A" (Resin) and "B" (Hardener) components, the mix ratio is far less critical than for traditional 2-part epoxy formulations. This allows the user to adjust working consistency at different temperatures. This variable ratio feature makes FLEXI-FILL 530 a true "all season" epoxy adhesive and sealant.

Flexi-Bond 540

Flexi-Bond 540

FLEXI-BOND 540 is a two component, 100% solids, moisture-insensitive epoxy bonding agent. Application of FLEXI-BOND 540 to wet or dry, properly prepared substrates assures tenacious adhesion of new toppings, patching compounds and tile bedding mortars when used in accordance with instructions. It may also be applied to steel, tile, wood and fiberglass. It can be used as a combination waterproof barrier and bonding agent when applying new concrete toppings over old concrete. It can be used to improve adhesion of tile bedding mortars to existing concrete, or may be used directly for tile bedding in combination with very fine sand. It can be used to prime and waterproof steel reinforcement prior t application of patching compounds or concrete pouring while improving adhesion of these materials. It can be used to penetrate and consolidate low strength floors, such as asbestos-cement or cinder concrete, and to improve adhesion of new toppings or patching compounds to same. It can be used to promote adhesion of concrete, bedding mortars or toppings to non-cementitious substrate, such as tile, plywood decking, or steel plate.

Pump X53i

Pump-X53 Series

PUMP-X53 is a multi-purpose, low modulus, moderate strength filler used for filling cavities, voids and cracks from a minimum of ¼" width up to approximately 18 inches. PUMP-X53i is an ultra-fine, moderate strength micro-injection grout which achieves high flow for efficient filling of small cracks and voids from a minimum width of approximately 1 mm to as much as several inches in thickness. Pump-X 53iE is an ultra-fine, expanding, non-polymer cementitious injection grout designed for filling small cracks and voids in sound concrete and masonry construction. Slight expansion after placement and before final set enables the material to force itself into close, positive contact with internal crack surfaces, where desired. PUMP-X-53iL is a softer, non-polymer, hydraulic lime grout, for use in Historic masonry restorations requiring repairs to lower strength brick and softer stone elements.
