Whether you have a concrete slab, exposed aggregate, asphalt or paverstone driveway, we're here to help. We specialize in removal and replacement of rotten wood expansion joints in driveways, sidewalks, patios, pool decks and commercial properties. We use only the best / proven products available. We will also caulk or fill any cracks or chips in the concrete and can optionally apply a seal coating to protect and add life. Call us to today to get started on your project!
Sonneborn SL2 is recommended for sealing and protecting wide expansion joints including pavement joints, driveway expansion joints, exterior deck expansion joints and such.
DMO installs Sonneborn (BASF) SL2 Elastomeric Polyurethane Sealant that is mixed onsite and poured in place. When cured, it forms a tough, resilient join seal that resists penetration, abrasion and remains flexible when exposed to weather and aging. Many popular colors are available to meet your specific design criteria.
Clear, water-based 20% silane penetrating sealerA-Tech Concrete Sealer protects concrete driveways, sidewalks and patios from water penetration. After application the concrete appearance will be unchanged. There is no gloss, sheen or surface layer to see. De-icing salts can cause the concrete to delaminate, spall and flake. EnviRoseal 20 Sealer stops chloride ion penetration by 94% (NCHRP Report 244 results.) The sealer has a long life because it penetrates below the surface of the concrete and will not wear away.
We are insured, professional and offer local references upon request.
Don't waste your money on extruded rubber to replace expansion joints!
Concrete joints are actually, hand-formed and are not nice, even, straight lines. So why put a pre-formed rubber gasket material in an empty concrete joint after the wood rots out? What if the width of the joints varies? What if the joint is narrow in some places and wide in others? What if the slabs have shifted due to drought conditions? What about exposure to the elements? Well, over time, the sun and elements will take their toll on anything, especially when the sun is also heating the slab and cooking the rubber / vinyl. The extruded rubber will eventually get hard and rigid and since it's not attached to the concrete, will fail.
Minor Cracks and Fractures
Small cracks and fractures 1/8" to ˝" wide are often difficult to patch using cement-based products. There's just no way to force the mixture into such a small opening. We use QUIKRETE® Concrete Crack Concrete Repair Caulk solve this problem.Gray Concrete Crack Seal is is placed directly into cracks in the slabs and optionally sanded to match existing slab. Concrete Repair Caulk can be applied to cracks in driveways, walkways, pool areas and patios. We always tell our customers, "We can't fix a crack but we can fill it".
We do not install Extruded Rubber / Pre-formed products:
Sure, it "sounds like a good idea", right? Putting a one size / fits-all straight extruded product in an empty, concrete expansion joint. There's only one BIG problem; expansion joints aren't perfectly symetrical! They come in all different shapes and sizes!
The fact is, the ONLY place we found a "perfect fit" for extruded rubber was in the DUMPSTER! Extruded rubber is a temporary fix (at best) and we do not recommend or install it.
We have been asked to replace extruded rubber that is not even one year old!
