Expansion joints in concrete, steel, masonry, timber and other structures are a critical element in overall building enclosure performance. Expansion or movement joints bisect the entire structure. This means that structural as well as building enclosure materials specified to waterproof, roof, clad, and cover the structure are divided by the intersecting opening that is the expansion joint. Consequently, expansion joint openings must be filled, sealed, and/or covered with materials that restore the function of the materials bisected.

ELECTRICAL: Sealing and insulating cable terminators, cable entries into switch boxes, machines etc. Covering and insulating underground and overhead twist-joints of aluminium conductors. Sealing flanges and cable entry portions of conventional cable-joints/moulds to make them moisture-proof. Sealing leakage in transformers, oil circuit breakers and other oil filled electrical switchgear equipment.

As soon as M–seal Sanitary resin/hardener is mixed, the chemical reaction starts immediately and it is advisable to start application on clean substrate as soon as mixing is over. Spreading of adhesive is easy in the first 5- 10 minutes, whereas smoothening of adhesive surface with wet cloth is possible up to about 20 minutes from mixing.

Sealing flanges and cable entry portions of conventional cable-joints/moulds to make them moisture-proof. Sealing leakage in transformers, oil circuit breakers and other oil filled electrical switchgear equipment. Joining metal parts to porcelain parts of suspension insulators and bonding broken porcelain insulators. Perhaps most critically, expansion joints will leak if they are not properly transitioned—between similar and dissimilar expansion joint systems at changes in plane and direction—as well as at the tie-ins to waterproofing and roofing membranes and at wall air-barriers and coatings. As a member of the Sika global family, Sika Emseal is now able to offer complete building enclosure and roof solutions that feature single-source expansion joint warranties between its roof expansion joint ( RoofJoint) and best-in-class roof membrane ( Sika Sarnafil), monolithic membranes ( Hydrotech MM6125) and Sika liquid applied membranes (Sika LAM). As one combined entity, M Seals will continue to invest in people, processes, facilities, systems, products and materials, and by coming together, can consolidate resources to aim to improve lead times, inventories, costs and supply chain logistics. Our sealant tapes are more robust than your average weather stripping–incorporating hydrophobic chemistry into a foam matrix that ensures durability and sealing while resisting compression set in a way not possible with traditional closed-cell gaskets.

Following the acquisition of both companies by Diploma Plc in 2019, DMR Seals became part of M Seals in July 2020. Having now worked together for two years, the company is putting the final piece of the puzzle in place, by joining the brands together under one name – M Seals. The resin & hardener are in a different, slightly contrast colour to help identify the uniform mixing. Mix thoroughly with both hands until a uniform off white colour is attained. It takes about 1-2 minutes to get a uniform mix for 50g of putty.
