Dynamic Probes, Wilton Cork

Dynamic Probes, Wilton Cork

TAL were brought in to complete 4 number dynamic probes at this property.

Because of the restricted access the rig that TAL uses was able to complete the probes at the rear of the property (having to take the rig through the garage to access the rear)

TAL were asked to complete probes internally on a house in Kanturk.

Because of the nature of the TAL probing rig we were able to complete the probes on 3 of the locations internally within the allowed work height.

Staged Pressure Grouting Uam Var Avenue & Glecoo Park

Staged Pressure Grouting Uam Var Avenue & Glecoo Park

TAL were involved from the start on these jobs from site investigation to being involved in costing the works and then completing them in a timely fashion to suit the clients.

Pressure grouting was completed in two stages to 3m deep.

Grouting & Anchors at Park Owen, Bonaventure & Mount Sion Road.

Grouting & Anchors at Park Owen, Bonaventure & Mount Sion Road.

TAL were involved be the main contractor to propose a system for the subsidence issues (due to escape of water) to the different houses. TAL brought on board one of their engineers to view the sites complete site investigation and propose a system for the works.

The works that were completed on site here were a combination system of grouting up the 2m to solidify this area and then the installation of anchors here through the solidified grouted section down to 6m. Also installed was one beam with piles.

Pressure Grouting Sligo County Library Foundation Repairs

Pressure Grouting Sligo County Library Foundation Repairs

TAL were involved in meeting with Sligo County Council and propose several solutions to the problem of a corner of the library that’s foundation was failing. (approximately 6m on each side of the corner).

It was agreed that the best solution that had been proposed for the works here was pressure grouting in various stages along the effected area of works. Once TAL set up on site and we completed two dynamic probes to verify the ground conditions.

Then TAL completed their drilling of 36 number boreholes along the effected area. these then were pressure grouted in stages under the existing foundation.

Hollowbar Piles @ a Shop in Athlone

.Hollowbar Piles @ a Shop in Athlone

TAL were involved with the engineers to install a low vibration pile system inside in a shop that was still in operation during the day.

A Dynamic probes were completed inside in the location of one of the pads in order to determine what the ground would be like.

Hollowbar piles (R38-500 bars) were then installed into the two pad locations. The works had to be completed outside nornal hours so as not to in-peed in the daily running of the shop.

There were two pads here and there were 4 piles installed into each pad. Plates and nuts were installed for connecting the piles to the pads.

Pier Anchors

Anchors (rock), Baltimore Quay Wall, Cork

Anchors (rock), Baltimore Quay Wall, Cork

 

TAL was involved in putting forward a design for the Baltimore Quay Wall stabilization works. The project involved anchors to be inserted at an angle from the edge of the quay wall back in and under the roadway (into rock). There were 15 number at 4M centres.

 

 

Due to the fact that this system was on the sea front, a 120 year life span was required. TAL used Dywidag 25mm GEWI solid steel thread bars with double corrosive protection.

At the top of each anchor was a square plate system, with nuts which were set to the right level before creating an in-situ concrete plinth along the front of the quay wall.

 

 

 

150mm Open Bored Piling Kenely Close, Model Farm Road, Cork

150mm Open Bored Piling Kenely Close, Model Farm Road, Cork

 

TAL were involved in this project to propose a piling system for the engineers approval. the works were for an extension to a block of semi-detached houses.

The system that was used here was a 150mm open bored pile.

Anchor & Shotcrete works at St Angelas College Cork

What started out as a straight forward underpinning job, ended up by abandoning the original scientifically designed underpinning process in midstream. Unsuspected variations in ground characteristics being the primary cause.

The objective was to cut an 8M shear / vertical wall immediately in front of a very large two storey convent.
Sub-base materials encountered included soft clays, very loose shale and dense rock, where each individually presented its own challenge. The solution was concluded at an on-site meeting and was entirely based / reliant on TAL’s experience / expertise in this area of construction.
A combination of shallow vertical pressure grouted solid bars, some permeation grouting, lateral anchors and layers of shot-crete was used, with complete effect.

Anchoring & Netting Rock Slope, Middle Road, Crosshaven, Co. Cork

Anchoring & Netting Rock Slope, Middle Road, Crosshaven, Co. Cork

 

Anchoring & Netting

Anchoring & Netting

Works consisted of drilling a grid of boreholes into a steeply sloped rock embankment and the installation of 38 No. “Ischebeck” ground anchors up to 5.5m in length. Ageogrid netting was placed over the face of the embankment and held in position with the ground anchors. The geo-grid netting was ‘seeded’ to encourage plant growth. This site had limited access and a steep terrain and a bespoke scaffolding arrangement had to be erected to access all areas of the slope. Within 2 meters of the slope there was the rear wall of a private dwelling that was in continuous occupation and had to be protected at all times.
