42 Salisbury (Southern UK & Export) Kings Lynn (Midlands Straight Edge & Testing Surface deformation measurement. A straight edge, approximately 3.0 metres in length, used to determine lateral surface regularity of a road or floor surface etc. Two versions are available: 1. A plain lightweight straight edge which can be placed on any surface to give a visual indication of level. 2. A lightweight straight edge equally supported at each end with an aluminium wedge, giving a set height between the concrete surface and straight edge. Using the straight edge with wedge blocks you can measure any vertical irregularity using an optional 2.5mm incremented wedge with a range of 12.5mm low to 12.5mm high. • 3.0m lightweight aluminium straight edge with carrying loops. • Available with or without 12.5mm wedge blocks. • Optional metric graduated measuring wedges marked every 2.5mm available. • Measuring range 12.5mm low to 12.5mm high Product code Description Size 26555 Version 2 -3.0m straight edge c/w with wedge support blocks. Order item 26570 for the complete kit. 3000mm x 76mm x 25mm 26570 Metric graduated wedge for measurement N/a Delamination Kit The design of the tool includes a telescopic extension pole and a precision-machined tool head. The rotary percussion tool, known as the Delam Tool, is easily rolled over the subject area, striking the surface numerous times with 30 percussion points acting as 30 separate hammers. Overhead areas, which are typically out of reach, can be tested in most applications by extending the telescopic pole. A set of companion tools which are used with the Delam Tool make the process of detecting, marking, measuring and documenting delaminated areas easier, faster and with greater accuracy. The need for an accurate method for non-destructive testing for delaminations in reinforced concrete has led to the development of rotary percussion.
