In this video we demonstrate one of many ways to replace or fix expansion joints of concrete driveways / walkways / sidewalks. Avoid cracking, settlements or concrete (driveway) demolition and replacement maintaining your concrete water tight. The woods in between your concrete slabs are not even meant to be there after the first year of your driveway pour. Wood rots and allows water to leak between your concrete and the "supporting soil", creating soil erosion. But sadly, home builders don't educate home buyers in the subject of concrete maintenance and people has to spend thousands of dollars in concrete replacement that could have been avoided. We use a sand, backer rod and polyurethane system to properly create an expansion joint.

Excellent. I wonder if you can use this product on a steep driveway without any problem or is there another product for these kind of driveways?

@oliveraguirreconcreterepai4826 3 года назад

Sloped driveways should technically be addressed with NON-SAG polyurethane. But these are rarely available in regular home improvement stores, the size and color options are limited. So if I was going to use the self leveling cartridges, I would start from the top and work towards the lower side, and stop the pour at about 2 to 3 feet away from the bottom end of the joint. Wait and assess how far the material flow, if it needs more, pour from the top, it is an art. Otherwise, you have to use professional grade products, where you mix a bulk portion of component A + B + a color pack. You can get bulk versions in Self Leveling and Non-Sag. And even the Self Leveling version of the bulk package is not as flowable as the self levelers from regular home improvement stores.

@tedwillard1595 4 года назад

Can you use self-leveling sealant on sloped driveways? If not, what do you use instead?

@oliveraguirreconcreterepai4826 4 года назад

Not recommended, but we have done it. If you use S.L. on a sloped driveway, make sure the slope is not too much and don't do it on a cold day, as the sealant will continue running off for 24 hrs. My trick on sloped driveways is to start the pour on the highest point and stop at least 2 feet away from the lowest point of the driveway, monitor how much the sealant is running on its own, it may flow all the way down and stop right at the lowest point, and if more sealant is required, apply it from upstream and let it run down. I suggest you to buy 1 single bottle of S.L. and do a test area. If it doesn't work, you only wasted a bottle and you can still switch to Non Sag solution, materials are compatible. Good luck!

@jsanchez2454 3 года назад

What do you feel about 'slab gasket'? Just started doing my research.

@oliveraguirreconcreterepai4826 3 года назад

All those prefabricated joint gaskets are good for driveways in a good condition. But if the driveway already has some settlements and gaps that vary in width, you can not use slab gasket, and the best is to use a liquid polyurethane that would adjust to the shapes of concrete, and truly making it water proof. Prefab gaskets work better on new driveways of driveways that have not gotten any settlements.

@colo5220 3 года назад

I have seen people using something like toilet paper to put on top of the new sealant before fully cured between two concrete slaps to protect people from stepping on the sealant and making footprint all over the concrete slaps. Do you know what that paper called? Thank you so much.

@oliveraguirreconcreterepai4826 3 года назад

You may be talking about the sticky mesh paper used for drywwall work. I never use it. It is still not stong enough to prevent someone to step on the fresh sealant. In fact, it may be messier to clean up after the "accident" if you have the mesh installed. Thats why i pour in a way the my sealant is 1/8 in below the walking surface. In case people walk or drive. But nothing as efficient as blocking your driveway with caution tape for at least 24 hrs after the pour. Material will continue drying for up to 3 days, but the crust will start to dry in the first 6 hrs.

any one can explain how the joint was saw cut? was it done by two line cutting? because saw blades dont come that wide thickness.

@bondpit8750 8 месяцев назад

It wasn’t saw cut, it was formed that way. In the days before continuous pours and diamond saw cutting expansion joints, it was common to place an organic expansion joint material between the formed slab pours. It’s still often used next to existing structures.

@angelsegura459 4 года назад

There's still a bit of a gap there. Will this create a tripping hazard? Why not add more of the base seal?!

@oliveraguirreconcreterepai4826 4 года назад

The most important is: If the expansion joint's width is 1 inch, the thickness of the sealant should not be more than 0.5 inches, otherwise, the sealant will not be elastic and will fail early. In this case, our customer didn't want the sealant to get stained with tire marks, so we poured 1/4 inch below surface level. You can pour the sealant all the way up if you want, just remember the magic width to depth rate "2 to 1".

Leveling the sand is not as important as leveling the backer rod. However, we hold a Chisel around 1inch away from the tip. Then, with the hand slightly touching the concrete surface, we drag it along the joint edge. But you can also use a cardboard gage....there are many ways, just get creative.

@glenncsr.88 3 года назад

Sika does not recommend putting sand before the backer rod.

@oliveraguirreconcreterepai4826 3 года назад

You are correct, sand under the backer rod is not a requirement. However, as a contractor, I want to ensure long life on my product and I go beyond the specs to do so. Adding sand under the backer rod does not stiffen the joint, therefore does not affect the elasticity and durability of the sealant. Sand would just add extra load bearing capacity to the joint system in case of a high heel or similar events.

@oliveraguirreconcreterepai4826 3 года назад

yup. Do not spray solvent based sealer over the material, it will re-emulsify the sealant (polyurethane). Its is pretty much the same with all brands of polyurethane sealants, not just this one. HOWEVER, there are solutions: a) Power wash and seal (solvent based) your driveway first and then install the exp. j. sealants. b) do the exp. j. sealants first and then do your surface sealer without touching the sealant, protect your sealant with tape, spray the whole driveway with sealer, then remove the tapes and brush the joints corners with sealer without touching the sealant. Anyways, sealants are not meant to be sealed.

@oliveraguirreconcreterepai4826 4 года назад

The sand we apply in the bottom is a quick foundation for the backer rod. The sand topping you see on other videos is for decorative purposes. Sand decorative toppings are not recommended as they reduce the flexibility of the sealant, leading to early cracking of the sealant

You blew it. You have to completely fill the joint up to the top edge of the concrete for driveways and walkways. Who would want sharp edges like you show exposed and a trap for dirt and Ice. The Ice will eventually break the concrete edges of the joint if they are not filled.

@oliveraguirreconcreterepai4826 4 года назад

Good point! But we are in Texas, so we have different conditions. How ever, we have seen how water drains off the joints and the driveway, so no ice should form. Also, tires stain and damage the integrity of the sealant over time, so our clients have opted to have a longer lasting solution by pouring the sealant 1/4 inch below concrete level. There is no one single solution. Thank you for your comment, I will make a note on the description.

@@fwood1231 if no visible damage, dont replace them. The whole point is water proofing your driveway. If you pour them too thick, they will not be elastic and will split away from the concrete.

If you joint width is 1inch, thickness should not be more than 0.5inch. Follow the magic numbers and they will last at least 5 years or maybe more.

@@LG-jy9nc if your driveway was just poured, the woods between the concrete slabs can provide some degree of water tightness for around two to three years. The minimum you should wait for the installation of an elastomeric sealant is around a month, because the concrete is still changing throughout that time (shrinkage). And about the material, regardless if it is self-leveling or non sag , you have to use an elastomeric sealant, we have found that polyurethane S. L. gives us the best results, just watch for the spills.
