2 Company Profile Tempo-PCE working with Uk Councils & large contractors since ShaDs, tunnels, bridges, new or refurbishment. Works over or on watercourses to the sea, canal or river. Specialising injec3on : Strengthening, waterproofing, ground injec3on. Poor access, watercourse or confined space & emergency structural works.

3 Company Profile Emergency call outs Complex brick, concrete & founda3on repairs. Specialist repairs par3cularly suited for listed structures. Members of Construc3on Line, CHAS, Safe Contractor & Acclaim.

4 Waterproofing Injection! High pressure crack injec3on! Slow leak or damp sealing in concrete or brick structures

5 Waterproofing Injection! General slow water sealing using flexible polyurethane! Can be used in brick with careful control of injec3on pressure

6 Waterproofing Injection! Using PU s or Acrylic for injec3on tubes or 3ght cracks! Water is pushed out as material expands

7 Waterproofing Injection! Potable water safe materials! Over or in watercourses, reservoirs with E.A & Waterboard approvals! 8 to 10mm holes to retain appearance of structure! Heritage structures can be waterproofed

8 Waterproofing Injection! Acrylic resin injected between steel soffit and concrete backfill! An3 corrosive proper3es

9 Waterproofing Injection! Drilled & injected from the underside no affect to traffic! Not possible for the u3lity companies to damage unless they really try

10 Waterproofing Injection! The injec3on equipment is small enough to fit down manholes! The same process can be used to bond concrete to steel using PU s

11 Waterproofing Injection! Acrylic water proofing can be used in service trays to surround services mixing in with the exis3ng back fill.! Material is like a jelly so will break up if the u3li3es require access! Injec3on from above or below

12 Waterproofing Injection! This typical expansion joint has a clay dam either side and the material is then poured in between. Water is able to drain across using the white pipe.

13 Fast leak Injection! Fast leaks! Small heading in flowing sands! Use of PUs to hold ground

14 Fast leak Injection! Fast leaks & flowing sands through the use of Acrylic or polyurethane injec3on

15 Stabilisation Injection! Ground stabilisa3on using PUs or Acrylic! Underpinning of founda3ons or subsidence! Tunnel or large void filling! Temporary support during a dig out of a heading, trench or cross passage.

16 Stabilisation Injection! Flowing sands: Using a method of injec3on of a structural polyurethane a safe working method is achieved

17 Structural Injection! Hard to access areas, generally without restric3ng live traffic! Thickening of arch barrel, using back fill to link to exis3ng masonry with the use of PUs! Removal of ring separa3on! Bonding to exis3ng saddle! Supported by independent assessment methods

18 Structural Injection Post injec3on & core crushing: This sample has been injected with a high flexible latex/ cemen3tous grout, material strength is 25N.! Fills voids! Retains flexibility of the structure! Retains appearance of structure! Bonds to exis3ng concrete saddle! Replaces missing mortar! Low pressure injec3on 0.5 to 40 bar site specific pressures! Marketed by Normet Uk as TamCrete 25FG! No jacking

19 Typical Injec3on Cost Example cos3ng for strengthening and waterproofing (not including prelims or site restric3ons): Cost per square metre, 180 to 245 m 2 Cost per linear metre, 990 to 1350 /m Example cos3ng for waterproofing only (not including prelims or site restric3ons): Cost per square metre, 110 to 150 m 2 Cost per linear metre, 630 to 830 /m

20 Structural Injection! Heritage approved blended hydraulic Lime grout injec3on can achieve a maximum strength of 12 Newtons! Lime injec3on similar to structural injec3on, can only be injected at low pressure, typically 1 to 3 bar.! Different types of lime grout for filling large voids and different strengths.

21 Structural Injec3on I GAP System from Normet! Unrestricted live traffic! Bonding brick rings together! Filling of voids! Waterproofing! Three Network Rail structures completed

22 On Site Monitoring A typical grout injec3on method is, start at base working working upwards, row by row.

24 On Site Monitoring Different materials can be indicated on the injec3on grids Injec3on maps reflect shape of structure to facilitate later iden3fica3on Exis3ng drawings can be introduced, illustra3ng individual areas and allowing addi3onal detail e.g. set 3mes Various injec3on phases can be shown South Service Tray, See rows 21- Abutment Abutment between between Vault Vault E1 E1 & E2, E2 See rows, See rows Vault Vault has has angled Abutement angled wall Abutement to east.
