Planning and Site Preparation for Concrete Methods

2017-3-18  The most important step in placing concrete is planning. Always plan every step before any concrete is delivered. Proper planning avoids delays, wastage, segregation and problems which develop from these. Proper concrete planning also eliminates problems of Delay, Segregation and Wastage. Workers on the site should always wear protective clothing, strong boots and

Stamped Concrete -Its Preparation and Construction

Preparation of Stamped Concrete Surface Preparation of stamped concrete surface is very simple but care should be taken. The process involved in several steps which are explained below. Preparation of Subgrade Soil The subgrade soil should be well compacted and even surface. Otherwise soil erosion may occur which effects the concrete slab.

Concrete surface preparation and coating selection

The concrete surface preparation method on a given surface will vary based on how contaminated, damaged or otherwise compromised it is. For instance, a surface may be in good enough shape to need relatively low-impact measures that will not alter the surface profile, such as vacuum cleaning, low-pressure water cleaning and washing or scrubbing
