CONSTRUCTION AND TESTING SERVICES
Services Offered:
Our staff has assisted ready mix concrete producers, engineers, architects and contractors in developing concrete mix designs using proportioning methods established by the Portland Cement Association and the American Concrete Institute that achieve the desired plastic and hardened concrete properties.
All of our concrete technicians are certified by the American Concrete Institute to assure field testing of plastic concrete is completed in accordance with ASTM procedures. In the field, our technicians maintain open communication with the contractor and ready mix concrete supplier to help assure that the best possible product is provided to the project.
In addition to testing fresh concrete, WGE can test properties of hardened concrete in our concrete laboratory or by using non-destructive test methods on the in-situ concrete. Our knowledgeable staff of engineers and technicians can provide consulting services to determine cause/s of concrete failures such as scaling, aggregate pop outs, cracking, etc.
The following is a list of some of the more common tests that our company can provide for hardened concrete:
- ASTM C-39 Compressive Strength Testing of Concrete Cylinders
- ASTM C-78/C-293 Flexural Strength of Concrete
- ASTM C-803 Penetration Resistance of Hardened Concrete (Windsor Probe)
- ASTM C-805 Rebound Number of Hardened Concrete (Schmidt Hammer)
- ASTM C-1202 Rapid Chloride Permeability of Concrete
Services Offered
Our experienced soil technicians will provide professional in-field testing for engineered fill and verification of the soil bearing capacity. In the unfortunate event that difficult soils are encountered during construction or if our subsurface exploration anticipates problem soils, the field technician/s will consult with our engineers to develop a course of action to rectify the situation in a timely manner so that the project can proceed.
The following is a partial list of some of the ASTM procedures that are conducted in our laboratory:
- ASTM D-698 Standard Proctor Method
- ASTM D-422 Particle Size Analysis of Soils
- ASTM D-1557 Modified Proctor Method
- ASTM D-1883 California Bearing Ratio of Laboratory Compacted Soils
- ASTM D-2166 Unconfined Compressive Strength of Cohesive Soils
- ASTM D-4318 Liquid and Plastic Limits of Soils
Services Offered:
Our staff can observe masonry construction to assure practices are in compliance with project specifications and cast the necessary specimens for laboratory testing. Our laboratory is equipped to test compressive strength of mortar or grout cubes, grout prisms and both grouted and ungrouted block prisms.
Services Offered:
Qualified personnel are available for observation of shop fabrication and field erection of structural steel. In addition, we can verify that bolts are correctly installed in accordance with the American Institute of Steel Construction.
Services Offered:
Our staff can provide the following services:
- Flatness and levelness measurements of concrete slabs
- Detection and location of embedded reinforcing steel
