Hi, Thank you for that informative write-up of pouring concrete more than concrete, I absolutely intend To achieve this asap. I've an existing concrete slab whose house floated down the river thirty many years in the past.
We wish to area a brick column on our driveway. Is that this possible? We will not set it specifically on a grass or dirt location. The concrete driveway is our only possibility. Many thanks for your help. - Karen
Look at 10 a lot more opinions... My aged walkway(twenty+yr)in cold wet Oregon is approx 8x25 and porch 8x6,the long extend at the moment has two cracks crosswise, which Will not trouble me but no other enlargement joints. Several of it can be roughed from weather plus some of it is still extremely smoothe under the eaves.
Don, regretably there isn't any true take care of for this. You could area and growth joint material from the house then pour concrete to fill the hole.
My garage and house are linked and were manufactured about 15 decades back. The basement (block) wall touches the concrete slab along the whole size from the garage. Water pools up within the spring about the garage floor due to a small spot and produces a moist wall during the basement.
Lana, when pouring a whole new slab or walkway it's import to slope the region away from the foundation of framework to allow for correct drainage. The base of the concrete need to pack down and also a layer of gravel installed to deliver drainage under slab.
Jan, Sakrete Sand Mix with Sakrete Bonder and Fortifier to be a primer/admixture is usually used for this mend. Sand Mix is good for repairs concrete mix truck capacity from two" right down to 1/2". The world needs to be correctly prepped by removing any bond breakers which include dirt, dust, caulk, particles, loose material, paint, stain, oil, and so forth. After the realm clean and you've got a strong sound substrate, apply a skinny layer of Sakrete Bonder and Fortifier using an affordable paint brush to prime the realm.
Sandman, Portland cement by by itself has no strength Unless of course blended with an aggregate and has no ability to be positioned in a thickness apart from as being a neat software in its raw point out. The present poured concrete for your table major will need to cure for 28 days before you decide to can utilize a topping material. The Sakrete Top ‘N Bond or Sakrete Flo-Coat is often used for resurfacing your concrete tabletop and can be utilized from ½” right down to a feather edge.
I have a phase-down front room that is certainly on the slab and 6" down below the remainder of the house. I plan To place 4" of Styrofoam, rebar, 2" of cement. What is the best bonding agent, cement to get for this job? - Bob
Walter, when 2 dissimilar substrates meet there need to be an expansion joint additional using the correct material to permit for that regular movement that may happen.
Chris, you would probably do better so as to add a French drain. Incorporating a suppress may well not fix the situation simply because concrete is porous.
Check out ten much more reviews... Eddy, unfortunately the paint will have to be fully taken off before you decide to could put a leading coat more than the existing slab. A bonding agent would not compensate for concrete mix for kitchen floor this. - Lee-Technological Support
Joni, Indeed the Flo-Coat could be used. The graceful areas will need to be abraded with a grinder or tool that should make a course profile. If you try to apply more than a very easy towel complete it could delaminate. Immediately after abrading the floor, pressure clean the whole spot to eliminate any free dust or particles. Make guaranteed that the floor is damp prior to deciding to implement the material.
Mark, however there is absolutely no way to tell if a crack is Lively or will return as soon as patched. Considering that the slab the ways are sitting on is deteriorating you might want to take into consideration getting rid of my response the slab all alongside one another and starting up from scratch.
