This stiffness can stop any further settlement. There is also extensive research needed on materials, techniques and methods.

Additional reinforcement can be added in-situ if needed. A case study is done to estimate the repair costs. CIE TK V07 33 For piling directly underneath the foundation, a pit is excavated below the foundation to provide a working space for the hydraulic jacks.

Layout of the new construction Two alternatives for the layout of the design of a foundation repair are presented on the next few pages of this paragraph.

From the two previous paragraphs, taking into consideration the above, it can be stated that rebars and tendons can both be used to strengthen an existing masonry wall in bending. Measuring bolts are installed and height measurements are taken. The possibility to partly subsidize the repair or getting a low interest loan varies per municipality.

Most importantly; the design must be feasible and able to compete with existing construction methods. New piles transfer the loads directly through the slab onto a bearing stratum.


Followed by a description of which repair methods are used in each municipality and what the average costs are per dwelling. Now funderinghserstel forces are transferred from the tendons to the concrete and the tendon is protected against corrosion Walraven, Supply and installation of all needed parts for a reinforced concrete beam.

It is, however, argued by contractors that when executing the work inside, floor slab piling is mostly a better option since concrete is relatively cheap, not much formwork is needed and there is instantly a new floor. This most often is the case in the Netherlands due to the already mentioned insufficient bearing capacity or deteriorated foundation. After preloading, the needle beam and part of the pileare encased with concrete for corrosion protection.

Notice that slow in this sense means that it can deal with deformation caused by, for instance negative friction. Street levels were often raised higher than the building site and courtyard Hogervorst, Situations have occurred where the cement mortar had deteriorated in strength to such an extent that the mortar could be removed just by scraping the surface Thorburn, Maanen and Gelder both think fundderingsherstel there is not much possibility to save costs within foundation research.

The performance of wooden pile foundation can decrease with time mostly due to biological attack. Sagging cracks tend to be the widest at ground level and with hogging the widest cracks will occur higher up towards roof level see figure 4.

Service life has known to exceed years Bijen, Sometimes they can be used directly or just need some modification. A plan of the repair design is given in the figure below. Recesses in the wall are needed to get the piles in. Tapering cracks indicate distortion. This fungus needs less oxygen to survive than do brown rot and white rot fungi and therefore prosper in wood exposed to soil and water Bijen, Costs for foundation- geotechnical- and environmental research and planning permission are not considered.


OATD: Klaver, T. – Foundation repair: In search of a more cost-effective construction method:

Other advantages of prestressing are Hendry, This leaves the possibility for floor heating and tiles can be applied. It depends on the structural condition, expertise of the contractor and the client requirements which method to choose.

Gouda has used the floor slap piling alternately hanboek can only be done if there are no interior bearing walls. Driving steel piles from the top is done with a fubderingsherstel jackhammer only for small diameter piles. The construction methods are categorized A1, A2, The old exisiting structure is a resource which is already there. From the weight calculations and the chosen design value for the pile bearing capacity it is determined that eight piles are needed per house.


This thesis covers the invention of the new method, explores the possibility to design a reinforced or prestressed masonry wall in bending and provides a cost estimate for comparison with current foundation repair techniques. This method is preferred by him only if the ground floor must be preserved. What does foundation repair cost? The findings of the extended research together with the case study should lead to answers concerning the innovative possibilities in foundation repair.

For wooden pile foundations in the Netherlands mainly pine and spruce were used.

Research Chapter 5 deals with the different repair methods for pile foundations. Cement mortar was introduced around
