How to Prevent Concrete Segregation? Wherever depth of concreting is more than 1.5 meters it should be placed through temporary inclined chutes. The angle of inclination may be kept between 1:3 and 1:2 so that concrete from top of chutes travels smoothly to bottom, use of small quantity of free water from top at intervals helps in lubricating the path of flow of concrete to bottom smoothly.

Steel strands are run through the concrete in a grid pattern. Each strand is housed inside plastic sheathing that protects the steel from corrosion and allows it to move during the stressing operation.

Do warm the concrete or use small doses of set accelerator to promote more uniform setting of the mix. This will make it easier to judge the timing of final finishing. Do take special precautions when ambient evaporative conditions are high and exceed concrete bleeding rates. Under these conditions, it's tougher to judge when bleeding is complete.

The house is not moving - or none I can tell anyways. The walkway is. Here are some pictures you can see old paint from where the concrete walkway used to be and how far it settled.
