Sealing In Sacramento: How To Remediate Cracked Concrete Playgrounds

If you have a playground in your backyard, you know it’s an excellent place for kids to play and have fun. However, if your playground is made of concrete, you may eventually start noticing some cracks.

Cracks in concrete can be dangerous, so it’s essential to remediate them as soon as possible. This blog post will review different ways to repair cracked concrete playgrounds.

Stay tuned for more on concrete repair for playgrounds!

Repair 1: Epoxy Injections

If you’ve spotted cracks with openings of 0.05 mm or wider, the epoxy injection method could be perfect for bonding them. The process involves epoxy resin being injected under the concrete crack, effectively sealing the cracks and minimizing the danger of any children getting hurt.

It’s worth noting, however, that any significant causes of the cracking need addressing before injecting any epoxy resin. Otherwise, the cracks will only continue appearing. You can’t resolve issues like silt contamination, leakages, and active or numerous cracks by injecting epoxy, so it’s essential to resolve those first.

Epoxy resin also demands skillful application, so ensure the contractor you’re working with has experience in concrete repair. You might also want to consider fireproofing protection for the area, as fire exposure and elevated temperatures can compromise the resin’s effectiveness.

Repair 2: Routing and Sealing

More common than epoxy injections are routing and sealing for concrete repair. These steps are simple and are suitable for only remedial repair for inactive cracks, without the need for tensile strength restoration.

The process includes enlarging the crack along its exposed face. The V-shaped groove is pushed to a minimum width of 6mm and 6 to 25mm depth. You can then fill the groove with hot sealant materials like epoxies, urethanes, silicones, asphaltic materials, polysulfides, or polymer mortars. Do not try to use cement grouting as it could result in future cracking.

When sealing the joint, make sure there’s enough room for movement in width to depth ratio. If you’re using hot joint sealants, ensure that they don’t melt or flow in operating conditions and bond properly with the concrete. The sealant should be durable and able to balance periodic expansion and contraction.

Repair 3: Stitching

True to its strange name, this process demands the use of metallic U-shaped wire to “stitch” the crack surfaces together. First, you drill several holes along the crack surface. Next, the metallic wire is passed through the said holes and anchored firmly into them with the help of grout or an epoxy-based system.

While this method might sound unconventional or crazy, it’s the easiest and most long-lasting solution to your problem if the crack is not too big. You must ensure that the contractor providing this service is experienced and reliable, as a botched job might cause more harm than good.
