2. Cured-in-place pipe - Wikipedia

   en.wikipedia.org/wiki/Cured-in-place_pipe

   The process of CIPP involves inserting and running a felt lining into a preexisting pipe that is the subject of repair. Resin within the liner is then exposed to a curing element to harden it and make it attach to the inner walls of the pipe. Once fully cured, the lining now acts as a new pipeline.

3. Concrete degradation - Wikipedia

   en.wikipedia.org/wiki/Concrete_degradation

   Repair principles which do not improve the strength or performance of concrete beyond its original (undamaged) condition include replacement and restoration of concrete after spalling and delamination; strengthening to restore structural load-bearing capacity; and increasing resistance to physical or mechanical attack.

4. Fusion bonded epoxy coating - Wikipedia

   en.wikipedia.org/wiki/Fusion_bonded_epoxy_coating

   The second most important part of FBE coatings is the curing agent or hardener. Curing agents react either with the epoxy ring or with the hydroxyl groups, along the epoxy molecular chain. Various types of curing agents, used in FBE manufacture, include dicyandiamide, aromatic amines, aliphatic diamines and organic acid anhydrides. [6]

5. Ductile iron pipe - Wikipedia

   en.wikipedia.org/wiki/Ductile_iron_pipe

   Protective internal linings and external coatings are often applied to ductile iron pipes to inhibit corrosion: the standard internal lining is cement mortar and standard external coatings include bonded zinc, asphalt or water-based paint. In highly corrosive environments loose polyethylene sleeving (LPS) to encase the pipe may also be used.

6. Leak detection - Wikipedia

   en.wikipedia.org/wiki/Leak_detection

   A leak appearing within an analytic region (a rule added to the camera) is immediately analyzed for its attributes, including thermal temperature, size, and behaviour (e.g. spraying, pooling, spilling). When a leak is determined to be valid based on set parameters, an alarm notification with leak video is generated and sent to a monitoring station.

7. Concrete slab - Wikipedia

   en.wikipedia.org/wiki/Concrete_slab

   For a suspended slab, there are a number of designs to improve the strength-to-weight ratio. In all cases the top surface remains flat, and the underside is modulated: A corrugated slab is designed when the concrete is poured into a corrugated steel tray, more commonly called decking. This steel tray improves strength of the slab, and prevents ...

8. Electrical liner integrity survey - Wikipedia

   en.wikipedia.org/wiki/Electrical_liner_integrity...

   Since the arc testing method is not dependent on water making good contact through the leak, it is more sensitive and comparatively easy to perform in most types of liner construction (ponds, Landfills, tanks etc.)than the water-based methods. The minimum sensitivity of the arc testing bare geomembrane liner integrity method is a pinhole leak.

9. Lift slab construction - Wikipedia

   en.wikipedia.org/wiki/Lift_slab_construction

   Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...
